Not knowing how people might respond to this post I didn't think to be clearer.
The RSS protocol works as well as it ever did. I'm not mourning the protocol. And yes there are sites that do publish feeds, some even full-feeds but many just excerpts.
What I am mourning is the future where people published for themselves and shared content via RSS. But companies that depend upon advertising are inimical to that future and they won (at least for now).
It's that future that I mourn for.
